실험 절차
To a solution of 8-chloro-3-ethyl[1,2,4]triazolo[4,3-a]piperazine (2.24 g) in MeOH (150 mL) was added PtO2 (1.36 g) and 10% Pd/C (0.63 g) at rt. The reaction mixture was stirred under H2 for 16 h at room temperature and filtered, and the filtrate was concentrated in vacuo and the residue was chromatographed with a silica gel column to give the title compound (0.71 g, 31.17%). The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 153.2 (M+1).
